A. Attach elevator to stabilizer as follows (Fig. 404 and 405):
(1)
Position elevator at stabilizer trailing edge.
(2)
At elevator hinge No. 1, install hinge bearing bolt with head outboard. Place washer under bolthead, bonding jumper next to washer, shims inside clevis and a washer under nut. Tighten nut 90 to 100 pound-inches. Align nut with cotter pin hole without exceeding 190 pound-inches, then install cotter pin.
(3)
At elevator hinge No. 2, install hinge bearing bolt with head outboard. Place washer under bolthead and nut, then tighten nut 90 to 100 pound-inches. Align nut with cotter pin hole without exceeding 190 pound-inches, then install cotter pin.
(4)
At elevator hinge fitting No. 5, install hinge bearing bolt with head outboard. Place washer under bolthead and under nut. At elevator hinge fitting No. 6, install hinge bearing bolt with head inboard or outboard. Place washer under bolthead, bonding jumper (on airplanes not incorporating SB 51-1011), next to washer and washer under nut. At both hinge locations, tighten nut 60 to 85 pound-inches. Align nut with cotter pin hole without exceeding 140 pound-inches, then install cotter pin.
(5)
On airplanes incorporating SB 51-1011, attach bonding strap approximately 7 inches inboard of hinge fitting No. 6. Clean surface to provide electrical bonding. Fillet seal fastener and bonding jumper end with sealant. After installation of bonding jumper, apply primer plus enamel to unpainted area on bracket. Optional procedure: Seal entire unpainted area on bracket with sealant.
(6)
Remove hoisting adapter from elevator front spar.
(7)
Install No. 3 and 4 hinge links. Ensure bushings are installed simultaneously with bolts.
(8)
At elevator hinges No. 3 and 4, install hinge bolt with head outboard. Install washer under bolthead and nut. Tighten nut 60 to 85 pound-inches. Align nut with cotter pin hole without exceeding 140 pound-inches, then install cotter pin.
(9)
Install seals adjacent to hinge fittings and along edge of elevator nose at stabilizer trailing edge ribs No. 1 thru 4. Adjust seals as follows:
(a)
Position and hold elevator faired with stabilizer during seal adjustment.
(b)
At stabilizer trailing edge rib No. 3, adjust flat seal to maintain 0.03 +0.03 inch clearance between seal and hinge fitting (Fig. 402, Detail A).
(c)
At stabilizer trailing edge rib No. 2, adjust flat seal to maintain compression of 0.00 to
0.03 inch.
(d)
At stabilizer trailing edge ribs No. 1, 2, 3 and 4, adjust bulb seals to maintain compression of 0.10 +0.04 inch (Fig. 402, Details B, D and E). At ribs No. 1 and 4, adjust bulb seals on nose ribs to maintain a gap of 0.03 +0.03 inch with rib (Fig. 402, Detail E). At rib No. 4, adjust bulb seals on nose ribs to maintain compression of 0.10\+0.10/-0.04 inch.

(f)
Connect tab push rods and tab lockout mechanism as follows (Fig. 409):
1) Secure aft end of frame to elevator front spar. Install inboard bolt with head facing outboard and outboard bolt with head facing inboard, with washers as required. Tighten nut on inboard bolt 40 to 55 pound-inches.
CAUTION: IF PUSH ROD NUTS ARE NOT TORQUED PROPERLY, THE PUSH RODS CAN BECOME DETACHED AND CAUSE DAMAGE TO THE ELEVATORS AND STABILIZERS.
